It should be understood that the server hardware Organization Chart shown in Fig. 1 is only an example of the applicable computer hardware Organization Chart of the embodiment of the present invention, the protection domain of the embodiment of the present invention is not limited to this.
Fig. 2 is the indicative flowchart of the communication means of one embodiment of the invention.The communication means can apply to multiple operating systems（Operation System, OS) communication system in, for example the communication system can have Fig. 1 shown in hardware structure.The communication system includes being separately operable an OS in management node, the first calculate node and the second calculate node, the first calculate node and the second calculate node.Wherein, the physical resource that management node, the first calculate node and the second calculate node specifically take in the communication system shown in Fig. 1 is not construed as limiting.For example, the cpu node shown in Fig. 1 can include one or more logic CPU.First calculate node, the second calculate node and management node can divide
Bao Kuo not at least one logic CPU.Further, management node, the first calculate node and the second calculate node can be the divisions on division or physical entity in logic.
201, the first calculate node sends communication mode analysis request to management node, and communication mode analysis request includes the mark of the first calculate node and the mark of the second calculate node.
202, management node is according to communication mode analysis request and communication mode reference information, the physical communication mode information between the first calculate node and the second calculate node is determined, communication mode reference information includes system topologies information and system physical resource allocation result.
For example, when the first calculate node or the second calculate node are to management node application physical resource, management node distributes corresponding physical resource so that calculate node is used according to the demand of calculate node for it, and records the physical resource Information that each calculate node is used（That is physical source distributing result）.In this case, management node can be used according to each calculate node of record physical resource Information and the system topologies information of communication system, determine available physical communication mode between calculate node.
Specifically, when calculate node starts, calculate node can by the information exchange between management node to its apply physical resource.Here it is described by taking the first calculate node as an example.When first calculate node starts, management node can be the first calculate node allocation identification, and the mark is returned into the first calculate node.Meanwhile, it is that the first calculate node distributes physical resource according to the demand of the first calculate node, and record the mark of the first calculate node and the corresponding relation of physical resource.
Similarly, can also be according to preceding method to management node application physical resource when the second calculate node starts., can also be according to preceding method to management node application physical resource when other calculate nodes start in addition, when communication system includes other calculate nodes.To avoid repeating, it will not be repeated here.
In addition, when being changed for the physical resource that the first calculate node or the second calculate node are distributed, management node updates physical source distributing result.For example, when the first calculate node adds application physical resource to management node, or management node is when releasing the part physical resource that the first calculate node is used, management node needs to update physical source distributing result.
Similarly, when the second calculate node adds application physical resource to management node, or management node is when releasing the part physical resource that the first calculate node is used, and management node is also required to update physical source distributing result.
In this case, in management node according to physical source distributing result and the system topologies information of communication system, when determining the physical communication mode information between the first calculate node and the second calculate node, management node can be in communication mode analysis request the first calculate node mark and the mark of the second calculate node, the mark and the corresponding relation of physical resource of the first calculate node in physical source distributing result
With the system topologies information of the mark and the corresponding relation of physical resource of the second calculate node, and communication system, the physical communication mode information between the first calculate node and the second calculate node is determined.
For example, management node can according to the calculating section of storage, mark and physical resource corresponding relation, determine the physical resource that the first calculate node uses and the physical resource that the second calculate node is used.So, with reference to the system topologies information of communication system, management node can determine the physical communication mode information between the first calculate node and the second calculate node.Wherein, the hardware annexation between the physical resource that the first calculate node uses and the physical resource that the second calculate node is used is included in the system topologies information of communication system,
203, physical communication mode information is sent to the first calculate node by management node.
204, the first calculate node is communicated based on physical communication mode information with the second calculate node.
For example, management node can send physical communication mode information to the first calculate node, initiate to communicate to connect from the first calculate node to the second calculate node.Or, after the first calculate node obtains physical communication mode information, assist to complete communication connection to management node request.
And for example, management node can send physical communication mode information to the first calculate node and the second calculate node simultaneously.So, the first calculate node and the second calculate node complete communication connection according to the mode indicated in physical communication mode information.
Based on above-mentioned technical proposal, in embodiments of the present invention, management node determines the physical communication mode information between two calculate nodes according to the topology information of communication system.So, in the case of there is hardware connection between calculate node, it can be communicated between calculate node according to foregoing physical communication mode information, and then improve communication efficiency.
Further, the physical communication mode between calculate node is unavailable, or when hardware connection being not present between calculate node, calculate node can be communicated based on ethernet communication protocol.For comparing ethernet communication mode, physical communication mode has higher efficiency of transmission and flexibility.Specifically, can be according to the attribute flexible allocation physical resource of the packet transmitted between calculate node, and then obtain different transmission speeds.
It should be understood that physical communication mode information can include all information set up between the first calculate node and the second calculate node required for physical communication connection, physical resource mark and communication mode mark that such as this physical communication connection takes.Or, physical communication mode information can only include the mark of physical communication mode.In this case, the first calculate node can be when setting up the physical communication between the second calculate node and connecting, then to this physical resource Information for using of communication of management node application.These alternate embodiments should all fall in the protection domain of the embodiment of the present invention.
It will also be appreciated that the first calculate node, the second calculate node and management node can be located at the processor shown in Fig. 1（102a, 102b) in same processor or different processors in, the embodiment of the present invention is not construed as limiting.
Alternatively, it is used as another embodiment, before the first calculate node sends communication mode analysis request to management node, the first calculate node judges whether include the physical communication mode information of the first calculate node and the second calculate node in the historical information set.In this case, when the first calculate node is to management node transmission communication mode analysis request, communication mode analysis request can be sent when it is determined that historical information does not include physical communication mode information, then to management node.
For example, when historical information includes physical communication mode information, the first calculate node determines physical communication mode information from historical information.When historical information does not include physical communication mode information, the first calculate node sends communication mode analysis request to management node, then receives physical communication mode information from management node.So, the first calculate node need not all ask management node parsing physical communication mode information, and then reduce overhead in each communication.
In addition, when the first calculate node supports asynchronous process, while communication mode analysis request is sent to management node, the other preparations that can be communicatively coupled.
Alternatively, as one embodiment, physical communication mode information is sent to after the first calculate node in management node, the first calculate node is by physical communication mode information record in historical information.
So, the first calculate node without asking management node parsing physical communication mode information, thus can reduce overhead in communication next time to obtain physical communication mode information directly from historical information.
In addition, when management node have updated physical source distributing result, the first calculate node can remove historical information, or set historical information to fail.So, the first calculate node can be communicated according to newest physical communication mode information, and communication efficiency can be improved to the full extent.
Alternatively, as another embodiment, physical communication mode information includes one kind in shared local memory communication method information, shared external memory communication method information and high speed interconnected communication mode information.
For example, shared local memory communication method information can include the start-stop address of the mark of shared local memory communication mode and the local memory for this allocation of communications.Shared external memory communication method information can include the start-stop address of the mark of shared external memory communication mode and the external memory for this allocation of communications.High speed interconnected communication mode information can include the mark of high speed interconnected communication mode and be the address of the high speed interconnecting channels used in this communication.
It should be understood that shared local memory communication mode refers to that two virtual machines are entered by shared local memory
Row communication.Shared external memory communication mode refers to that two virtual machines are communicated by shared external memory.High speed interconnected communication mode refers to that two virtual machines are communicated by high speed interconnecting channels.
Alternatively, as another embodiment, communication mode reference information also includes system physical resource using status.
For example, management node determines all physics communication modes between the first calculate node and the second calculate node according to physical source distributing result and system topologies information.Then, management node combination physics resource using status, analyzes foregoing all physical communication modes, and the physical communication mode information finally determined.
Specifically, H does not have the highest priority of shared local memory communication mode, and management node may determine that whether local memory remaining space is more than default wealthy value.When internal memory remaining space is more than default wealthy value, physical communication mode information can be defined as by the mark of shared local memory communication mode and for the communications address information of this allocation of communications.
On the contrary, when internal memory remaining space is less than default wealthy value, management node can judge whether the high communication mode of preferential level can use according to the use state of physical resource.Wherein, determination methods are similar with the method being described above, and to avoid repeating, will not be repeated here.
Alternatively, as another embodiment, communication mode analysis request also includes type of data packet and data package size.
In this case, the type of data packet and data package size that management node can combine in communication mode analysis request are that the first calculate node determines physical communication mode information.For example, when packet is smaller, high speed interconnected communication mode can be selected.When packet is larger, local memory communication mode is shared most fast.In addition, with reference to the instantaneity requirement of type of data packet, namely packet, management node can select a more particularly suitable communication mode for the first calculate node.
Alternatively, as another embodiment, system topologies information includes the one or more in Schema information, local memory information, outside shared drive information, decoupling framework high speed interconnection information and the network interconnection information of central processor CPU.
The embodiment of the present invention is described in detail below in conjunction with specific example.It should be noted that these examples are intended merely to help those skilled in the art to more fully understand the embodiment of the present invention, the scope for the embodiment that is not intended to limit the present invention.
Fig. 3 is the indicative flowchart of the communication means of another embodiment of the present invention.
301, when the first calculate node starts, to management node application physical resource.
302, management node is that the first calculate node is distributed after physical resource, is returned to the first calculate node
Allocation result.The allocation result includes the mark of the first calculate node and the corresponding relation of physical resource.
303, when the second calculate node starts, to management node application physical resource.
304, management node is that the second calculate node is distributed after physical resource, and allocation result is returned to the second calculate node.The allocation result includes the mark of the second calculate node and the corresponding relation of physical resource.
305, when the first calculate node prepares to be communicated with the second calculate node, first inquire about the historical information of setting.If historical information includes the physical communication mode information between the first calculate node and the second calculate node, the first calculate node can be directly to determine the physical communication mode information from historical information.
If not including the physical communication mode information of the first calculate node and the second calculate node in historical information, step 306 is performed.
306, the first calculate node sends communication mode analysis request to management node.
307, management node is according to the physical communication mode information that communication mode analysis request is between the determination of the first calculate node and the second calculate node.
For example, physical resource Information and the system topologies information of communication system that management node can be used according to each calculate node of record, determine available physical communication mode between calculate node, and then determine physical communication mode information.
308, management node sends physical communication mode information to the first calculate node.
309, the communication connection that the first calculate node is set up between the second calculate node according to physical communication mode information, to be communicated.
Based on above-mentioned technical proposal, in embodiments of the present invention, management node determines the physical communication mode information between two calculate nodes according to the topology information of communication system.So, in the case of there is hardware connection between calculate node, it can be communicated between calculate node according to foregoing physical communication mode information, and then improve communication efficiency.
Fig. 4 is the schematic block diagram of the communication system of the embodiment of the present invention.Communication system 40 includes management node 401, the first calculate node 402 and the second calculate node 403.For example, the communication system 40 can have the hardware structure shown in Fig. 1.Wherein, the physical resource that management node 401, the first calculate node 402 and the second calculate node 403 take is not construed as limiting.For example, the CPU node shown in Fig. 1 can include one or more logic CPU.First calculate node, the second calculate node and management node can include at least one logic CPU respectively.An OS has been separately operable in first calculate node 402 and the second calculate node 403.Further, management node 401, the first calculate node 402 and the second calculate node 403 can be the divisions on division or physical entity in logic.
First calculate node 402, for sending communication mode analysis request, communication to management node 401
Mode analysis request includes the mark of the first calculate node 402 and the mark of the second calculate node 403.Management node 401, for according to communication mode analysis request and communication mode reference information, the physical communication mode information between the first calculate node 402 and the second calculate node 403 is determined, communication mode reference information includes system topologies information and system physical resource allocation result.
For example, when the first calculate node 402 or the second calculate node 403 apply for physical resource to management node 401, management node 401 distributes corresponding physical resource so that calculate node is used according to the demand of calculate node for it, and records the physical resource Information that each calculate node is used（That is physical source distributing result）.In this case, management node 401 can be used according to each calculate node of record physical resource Information and system topologies information, determine available physical communication mode between calculate node.
Specifically, when calculate node starts, calculate node can by the information exchange between management node 401 to its apply physical resource.Here it is described by taking the first calculate node 402 as an example.When first calculate node 402 starts, management node can be the allocation identification of the first calculate node 402, and the mark is returned into the first calculate node 402.Meanwhile, it is that the first calculate node 402 distributes physical resource according to the demand of the first calculate node 402, and record the mark of the first calculate node 402 and the corresponding relation of physical resource.

It should be understood that shared local memory communication mode refers to that two virtual machines are entered by shared local memory
Row communication.Shared external memory communication mode refers to that two virtual machines are communicated by shared external memory.High speed interconnected communication mode refers to that two virtual machines are communicated by high speed interconnecting channels.
Alternatively, as another embodiment, communication mode reference information also includes system physical resource using status.
For example, management node 401 determines all physics communication modes between the first calculate node 402 and the second calculate node 403 according to physical source distributing result and system topologies information.Then, management node 401 combines physics resource using status, analyzes foregoing all physical communication modes, and the physical communication mode information finally determined.
Specifically, H does not have the highest priority of shared local memory communication mode, and management node 401 may determine that whether local memory remaining space is more than default wealthy value.When internal memory remaining space is more than default wealthy value, physical communication mode information can be defined as by the mark of shared local memory communication mode and for the communications address information of this allocation of communications.
On the contrary, when internal memory remaining space is less than default wealthy value, management node 401 can judge whether the high communication mode of preferential level can use according to the use state of physical resource.Wherein, determination methods are similar with the method being described above, and to avoid repeating, will not be repeated here.
Alternatively, as another embodiment, communication mode analysis request also includes type of data packet and data package size.
In this case, the type of data packet and data package size that management node 401 can combine in communication mode analysis request are that the first calculate node 402 determines physical communication mode information.For example, when packet is smaller, high speed interconnected communication mode can be selected.When packet is larger, local memory communication mode is shared most fast.Another sunset is foretold, and with reference to the instantaneity requirement of type of data packet, namely packet, management node 401 can select a more particularly suitable communication mode for the first calculate node 402.
Alternatively, as another embodiment, system topologies information includes the one or more in Schema information, local memory information, outside shared drive information, decoupling framework high speed interconnection information and the network interconnection information of central processor CPU.
